| Resistant varieties have been the preferred means to control Magnaporthe grisea, the causal organism of the rice blast disease. The objective of this study was to examine the degree of diversity of the pathogen in different rice growing regions of São Paulo State, Brazil. Blast samples collected from rice varieties in three different regions (Tremembé, Mococa and José Bonifácio) were analyzed for race structure employing the Japanese rice differentials. The highest degree of virulence diversity was observed in Tremembé with 22 different races in three different varieties. Furthermore, no resistance gene in the Japanese differentials was effective to all isolates of M. grisea from São Paulo State. |

| The objective of this work was to evaluate the possibility of obtaining recombinant inbred wheat lines more resistant to preharvest sprouting, independently of colour genes, in three red-grained Brazilian wheat populations. The results showed statistical significance among lines within all populations, which presented a normal distribution and transgressive segregation for preharvest sprouting. The normal distribution of the lines from all red-grained populations suggests that sprouting, excluding the genes expressing seed coat pigmentation, is, probably, controlled by many genes. These findings also indicate that it may be possible to improve resistance to preharvest sprouting, independently of the colour genes. |

| ABSTRACT: Quillaja genus (Quillajaceae family) is endemic to South America, where is represented by two species, Quillaja saponaria and Quillaja brasiliensis. One outstanding characteristic of these forest tree species is their production of saponins, a family of amphipathic glycosides, involved in the defensive response of plants against biotic and abiotic factors. Saponins are metabolites of economic importance due to their chemical and physical properties. Basic and applied research efforts performed during the last decades, mainly on Q. saponaria, have placed these compounds as an important raw material in industrial areas, such as food and beverage, cosmetics, vaccine production, biopesticides, among others. In this review, we summarize information on... |

| La roya amarilla (Puccinia striiformis f. sp. tritici) del trigo (Triticum aestivum L.) causa pérdidas importantes en rendimiento en los Valles Altos de México, debido a que el hongo puede evolucionar y vencer la resistencia de las nuevas variedades. Por tanto, se estudio la virulencia de este patógeno en los ciclos Primavera-Verano (P-V)/2005, 2006 y 2007 en los Valles Altos de México. Se recolectaron hojas y espigas infectadas con el hongo causante de la roya amarilla de zonas productoras de los estados de Tlaxcala, Hidalgo, Puebla y el Estado de México. Las muestras se procesaron en el Centro Internacional de Mejoramiento de Maíz y Trigo (CIMMYT) ubicado en El Batán, Texcoco, Estado de México. Para identificar las razas fisiológicas se usaron 14 líneas... |

| Osteosarcoma (OS) is the most common primary bone malignancy, but current therapies are far from effective for all patients. A better understanding of the pathological mechanism of OS may help to achieve new treatments for this tumor. Hence, the objective of this study was to investigate ego modules and pathways in OS utilizing EgoNet algorithm and pathway-related analysis, and reveal pathological mechanisms underlying OS. The EgoNet algorithm comprises four steps: constructing background protein-protein interaction (PPI) network (PPIN) based on gene expression data and PPI data; extracting differential expression network (DEN) from the background PPIN; identifying ego genes according to topological features of genes in reweighted DEN; and collecting ego... |
